TRIX OF THE SAID PETER GABRIEL, DECEASED.

WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 484,418, dated October 18, 1892.

Application filed April 25,1890. Serial No. 349,500. (No model.)

To all whom it may concern.-

Be it known that 1, PETER GABRIEL, of Helena, in the county of Lewis and Clarke and State of Montana, have invented certain Improvements in Window-Screens, of which the following is a specification.

This invention relates to that classof window-screens which consist of two frames covered with wire-cloth or equivalent material and connected by sliding joints, so that they may be extended to fit openings of different SIZES.

The object of the inventionis to adapt screens of this character to be extended in different forms so as to fit openings of considerable height and width as well as openings of extreme width and limited height; and to this end the invention consists, essentially, in connecting the two oblong rectangular frames by sliding joints of such construction that the frames may be extended in the direction of their width or of their length, as required.

In the accompanying drawings, Figure 1 is a perspective view of my improved screen as it appears when extended horizontally. Fig. 2 is a vertical cross-section on the line 2 2 of Fig. 1. Fig. 3 is a horizontal section on the line 3 3 of Fig. -1. Fig. 4 is a horizontal section on the line 3 3 with the two frames in position for vertical instead of horizontal extension. Fig.5 is a face view of one of the frames. Fig. 6 is a rear face view of the companion frame.

Referring to the drawings, A and B represent two oblong rectangular frames constructed of wood or other appropriate material and each covered in the ordinary manner with wire-cloth or other pervious material.

The frame A has its vertical side bars a and a provided each with a vertical groove or channel 0. in the right-hand side. The horizontal top and bottom bars a and 0. of this frame are each grooved horizontally in the upper edge, as shown at a Aspace or opening a is left between the vertical and horizontal bars at the upper left-hand corner of the frame and a corresponding space a. left between the vertical and horizontal bars at the lower right-hand corner .of the frame, as clearly shown in Fig. 5. V

The frame B is provided with grooves b in the upper edges of its horizontal bars and with grooves 19' in the left-hand edge of each vertical bar. Spaces b and b are left between the horizontal and vertical bars at the upper left-hand and the lower right-hand corners, as shown.

The two frames are connected as shown in Fig. 1. When it is to be extended horizontally, the horizontal grooved bars of the frame A enter and slide within the horizontal bars of the frame B. This permits the frames to be closed one over the other or of one being extended nearly its entire width beyond the other. The horizontal separation of the frames is prevented by the contact of the vertical bars at their overlapping edges, and in like manner their vertical separation is prevented by the contact of the horizontal bars at their overlapping edges.

If the screen is to be extended vertically instead of horizontally, the frame B is closed inward over the face of frame Auntil the two frames are flush at their edges, as shown in Fig.4. This causes the vertical grooved rails of the two frames to interlock and brings a vertical bar of each frame opposite the corner-opening in the other, thus allowing the frameB to slide upward beyond the frame A, as indicated in dotted lines in Fig. 1.

It will be seen that the essence of my construction lies in providing the frames with two series of sliding joints or sliding connections at right angles to each other, so that the one frame may be extended horizontally or vertically in relation to the other, and it is manifest that the details of these sliding joints may be variously constructed without departing from the limits of my invention.

In constructing my device the skilled mechanic will understand that the sliding joints are to be so closely fitted that the friction between the sliding surfaces will maintain the parts in the positions to which they may be adjusted.

Having thus described my invention, what Iclaim is- 1. A window-screen consisting of two oblong frames covered with wire-cloth or equivalent material, said frames united by sliding connections and adapted to be moved bodily 5 one upon the other in the direction of their length and also in the direction of their width, whereby the one frame may be extended either transversely or longitudinally beyond the other at will.

10 2. In combination, two oblongscreen-frames connected to slide bodily one upon the other in two directions at right angles to each other,

whereby the frames may be extended longiv tudinally or laterally at will.

In testimony whereof I hereunto set my :5

hand, this 21st day of March, 1890, in the presence of two attesting witnesses.
